BUFFINGWWHEEL.

SPECIFICATION forming part of Letters Patent No. 306,463, dated October14:, 1884.

Application filed August 1l, 1883.

To a/ZZ whom t may concern:

Beit known that I, ROBERT BINNS, of South W'indhannin the county ofVindham and State of Connecticut, have invented certain new and usefulImprovements in BuflingVheels; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, whereby aperson skilled in the art can make and use the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon.

Like letters in the figures indicate the same parts.

Figure l is a plan view of my buffing-wheel, the line of stitching beingindicated by conventional broken lines. Fig. 2 is a view incross-section of one form of my completed buff ing-wheel formed oftextile fabric or filamentous material; and Fig. 3 is a view similar toFig. l, but with the outer layer of fabric removed to show the scraps orpieces of which it may be made.

Heretofore buffwheels have been made of pieces of textile, fibrous, andother material united by sewing through and through the mass ofsuperposed pieces in radial lines or concentric circles. In using suchwheels the workmen open the periphery of the wheel to loosen the pieces,and as the wheel is worn, its periphery being made most dense by and inthe lines of stitching, it follows that there will be a constantvariation and inequality rin the density and effectiveness of the activesurface of the wheel. This defect produces bad work. Furthermore, withthe radial stitching, as the wheel wears the stitclrthreads whip out andcut the workmans hands, and this defect is, if anything, aggravated bysewing in concentric circles. Now, in attempts to overcome thesedefects, I have found that by sewing the material of the wheel togetherby stitches arranged in a spiral line continuous from the rim of thewheel. to its center I get awheel of practically (No model.)

uniform density throughout, and in which the whipping out ofthe stitches is very materially, if not altogether, removed.

lMy invention therefore consists of a buffwheel of textile or otherfabric or material sewed together in superposed pieces by stitchesextending spirally from rim to center, all as hereinafter particularlyset forth and claimed. In making my wheel I take first a layer or disk,a, of textile fabric, as cotton, and upon it place a given quantity ofrags, scraps, or fragments of fabric or filamentous material, b, atrandom, taking care only to place the pieces in comparatively evenlayers when textile materials are used, and upon this mass I lay asecond outer whole layer or disk, c, and compress the whole mass, andsecure it by one or more spiral lines of stitching, d, extending fromthe rim to the center, the stitches going through and through the saidmass. These thread-stitches, so arranged, serve to hold the mass compactfrom the center to the very edge 6- ofthe wheelthus preserving acircular periphery, its equal density, and insuring its wea-rA ing downevenly to the clamps attaching it to its driver. The Woof-threads of thepieces of cloth will extend in every direction, and, as distinguishedfrom a wheel having its layers of whole cloth in which the woof-threadswill almost unavoidably run parallel in the several layers, my wheelwill to this extent be further enhanced in its tendency to wear downevenly. After the mass is sewed it is cut to shape and provided with anarbor hole or hub.

A bufng-wheel composed of rags, scraps of textile fabric, filamentousmaterial, or the like, 8o compressed and united by one or more spirallines of stitching, substantially as described.
